Oil
It's not a matter of if the ship is going down, it's just a matter of when.
"The economists all think that if you show up at the cashier's cage with enough currency, God will put more oil in ground," Deffeyes said.
Oil and car companies have spent the last 50 years working together to make as much money as possible (read:by taking it from your pocket). It's quite obviously a mistake that they haven't been making a real effort to produce more efficient cars, and vehicles that use alternatvie forms of engery.
When faced with this problem, what do you they do? Deny it exisits.
"A man who has committed a mistake and doesn't correct it, is committing another mistake." Confucius
